I have several of those and ALL have the same failure: this tiniest gear on the axis of the stepper is broken and split. > I read several threads regarding the pens.

Any tips on those? (I am over-cautiously > protecting the working pens, I remove them from the printer and re-cap immediately after > I am done printing). No, once they dry out you are out of luck. I remember giving them for refill at local “fountain pens repair shop” some good time ago, but as you might guess this place doesn’t exist for decades now. There are supposedly ways to refill them @ home (basically if you can open them in a non-desctrutive manner you should be able to revive them too) but I never tried. What I had in my mind for some time but never got to finish it in the end was to design an adapter for the modern "gel type" ball pen inserts. I even started to lathe the back part but got stuck with the front part. > The disk image is here: https://dl.dropboxusercontent.com/u/39319567/CBM1520_programs.d64%c2 Kiitos! I need to find one day a source of those damned tiny gears or I print them one day myself ;-) -- SD! Message was sent through the cbm-hackers mailing listReceived on 2014-06-24 21:00:03
